Santa Clara County residents and businesses have made significant investments in its transportation infrastructure. The Transportation Systems Monitoring Program (TSMP) was initiated by VTA’s Technical Advisory Committee and approved by the Board of Directors in 2008 as a means of monitoring the conditions and performance of selected transportation system networks and assets. The TSMP and annual reports were developed in response to concerns raised by local jurisdictions on the ability and resources needed to maintain the County’s transportation infrastructure to acceptable standards.
Other benefits include:
- Enable the County and external stakeholders to better understand the performance of the County’s transportation system and effectiveness of the investments.
- Communicate progress towards stated transportation system goals and objectives.
- Provide additional context for future funding and policy decisions.
The TSMP follows the asset management principles of Fixing America’s Surface Transportation Act (2015) and the Infrastructure Investment and Jobs Act (2021), the federal reauthorization transportation funding programs that emphasizes performance-based management of transportation infrastructure assets at the state and local levels, as well as California’s Transportation Asset Management Plan and California Senate Bill 1 (SB1) that establishes performance targets for California Transportation Commission State Highway Operation and Protection Program (SHOPP) Guidelines.
The 2025 TSMP report builds on the data research presented in previous reports with a focus on the following areas:
- Local Street Pavement Conditions
- Freeway Litter and Graffiti Maintenance
- Roadway Safety (Collisions) Conditions
- Clean Energy Station Inventory
The 2025 Transportation Systems Monitoring Report is the 15th edition since the first report was released in 2010. Since then, the reports have expanded to include new data as it became available:
- 2010 (1st edition) - Introduced basic performance measures for consideration
- 2011 (2nd edition) - Introduced monitoring of litter and landscape conditions on the highways.
- 2013 (3rd edition) - Featured an inventory of traffic signal systems and introduced monitoring of express lanes.
- 2014 (4th edition) - Featured a new dashboard report format, key performance measures table, pavement, bridge, and litter and landscape monitoring sections, new safety section and revised air quality section.
- 2015 (5th edition) - Featured an expanded litter and landscape section.
- 2016 (6th edition) - Added ramp metering inventory and featured green bike lanes materials and applications.
- 2017 (7th edition) - Added a section to track the most frequently reported problems from local jurisdictions.
- 2018 (8th edition) - Added Commute and Time Spent in Congestion section to track performance of major corridors in the County, and new performance metrics for monitoring litter and graffiti along the highways.
- 2019 (9th edition) - Reformatted to a more data driven report with graphic information representation over text. The report was also condensed to focus on areas of importance to communities: 1) Pavement, 2) Freeway Litter Landscape, and Graffiti Maintenance, and 3) Roadway Safety (Collisions).

About the Data
The information presented in the TSMP Reports leverages data extracted from a variety of transportation references and from local, state, regional, and federal agencies, as well as non-profit organizations like the Joint Venture Silicon Valley Institute for Regional Studies who produces the annual Silicon Valley Index Reports. In addition, a self-assessment survey was used to gain insight from local agencies on their ability to maintain roadside assets within their jurisdictions. The performance measures and sources used for this report are listed in the Notes Section.
